3D data can be displayed and navigated using the ArcScene Application. in this case we will add an aerial photograph (e.g. aerial 5 in the tutorial data folder) . About This Tutorial. This article describes the steps required to load and display topographic, geologic, and cultural data in ArcScene and presents several. This tutorial is an introduction to ArcGIS 3D Analyst, an extension for ArcGIS. The extension needs to 1 From the 3D Analyst toolbar click the ArcScene button.

Later we will investigate how tutoria can create and preserve view corridors after existing buildings are removed in anticipation of developing a new transit-oriented development. From the pulldown menu on the Draw toolbar, choose Convert Graphics to Features. The Tools toolbar includes several navigation tools used to manipulate the observer and camera target positions. Use this image as a beginning guide to familiarize yourself with the ArcScene environment. This wil make it very easy to register the image as with other layers as we export them to other tools.
GIS Manual: Beginning a 3D Modeling Project in ArcGIS
The main reason for the arcdcene premise is that the ground plan of the model is going to be exchanged as an image. When saving, be sure to set Save Files of Type to Shapefile. We use this tool to export the buildings and the frame from your scene.
There is no 3D globe surface provided in ArcScene. Because we want to arcscenf a nice compact 3d model, we will export a clip of the elevation model using the same extent that we used to export the groundplan image. If you export an image from arcmap with the Georeference option checked. For the context image, you don’t necessarily need a very high-resolution image. Note that arcscenr window controls can be moved around the display to customize your view.
As we have explained above, one element of our site model will be an image of the groundplan for our site and its context. Think about the sort of grapnhical hierarchy thou would want in a reference image that will be draped on an aerial photo in your tutogial.
Go to the Layer Properties for your groundplan and in the Symbology properties, change Stretch to None, and uncheck the option for Gamma Stretch.
Our rough 3d model can be useful for investigating how places interact visually. How will the removal or addition of buildings create or block views?
Introducing the ArcScene user interface
Dockable windows collapse from the 3D view when not in use. Then we have everything we need to make a nice compact 3d model of our site! Our clipped dataset is going to include: Our T sign is created by making a copy of our point layer. In an earlier tutorial on Digital Elevation Modelswe got some experience with GIS data sources that represent the elevation of the terrain.
Name this layer Removed Buildings Turn off your Groundplan so that you can see the building shapes. With this in mind, we should create a new folder system that will hold all of this work.

In addition, certain tools and options displayed here may be specific to ArcScene and therefore not available in other applications. Save rutorial buildings as a shapefile in your data folder. You can use the Advanced symbol swettings to read the height for each symbol from an attribute.
ArcScene is very similar to ArcMap, except it has some additional features for visualizing and navigating data in 3D. Note that if you het a cryptic error message when you try to do this it is probably because you need to change the File Type from geodatabas feature arscene to Shapefile.
We are going to start with a large city-wide repository of data representing terrain, buildings and the materiality of the ground. To list data by source will display the storage path above the layers.
Make sure that the Clamped to Ground option is unchecked.
From this we will clip out a smaller dataset that we can play with in 3D without over-burdening a modest computer. You can quickly learn the name and more about its capabilities. You may want to use other overlays with transparency to colorize the photograph or to include details for some other Arcscehe layer that you have.
Like above, there are a few ways of doing this. Export your Clipped Buildings layer. Export your Frame polygon with the Clamped to Ground tuutorial checked. Then we can navigate to different places in the model check whether the sign is visible. Inspect the model to see if it makes sense. Thinking about it another way, many programs like AutoCAD and Sketchup will choke if you try to drape a texture with more than, say x pixels These tools optimize arcacene with the 3D view and your data.
Your Groundplan image can be added to Google Earth as am Tuforial Overlay note that your frame polygon will make it very easy to register this overlay. Note that arcscene offers a special box for adjusting the resolution of your exported image in the View Size box at the bottom left corner of the export image dialog.
Fix it Symbology properties of your adcscene, setting Stretch to none as discussed above. Get to know the ArcScene user interface. Thererfore, it is better to choose a new name for your exported image iof you have to export more than once.
